Rule 4-1.10 — Imputation of Conflicts of Interest; General Rule

Comment (verbatim from The Florida Bar)

Definition of “firm”
There is ordinarily no question that the members of an
organization’s law department constitute a firm within the meaning
of the Rules of Professional Conduct. However, there can be
uncertainty as to the identity of the client. For example, it may not
be clear whether the law department of a corporation represents a
subsidiary or an affiliated corporation, as well as the corporation by
which the members of the department are directly employed. A
similar question can arise concerning an unincorporated
association and its local affiliates.
Similar questions can also arise with respect to lawyers in
legal aid. Lawyers employed in the same unit of a legal service
organization constitute a firm, but not necessarily those employed
in separate units. As in the case of independent practitioners,
whether the lawyers should be treated as associated with each
other can depend on the particular rule that is involved and on the
specific facts of the situation.

Where a lawyer has joined a private firm after having
represented the government, the situation is governed by rule 4-
1.11(a) and (b); where a lawyer represents the government after
having served private clients, the situation is governed by rule 4-
1.11(d). The individual lawyer involved is bound by the rules
generally, including rules 4-1.6, 4-1.7, and 4-1.9.
Different provisions are thus made for movement of a lawyer
from 1 private firm to another and for movement of a lawyer
between a private firm and the government. The government is
entitled to protection of its client confidences and, therefore, to the
protections provided in rules 4-1.6, 4-1.9, and 4-1.11. However, if
the more extensive disqualification in rule 4-1.10 were applied to
former government lawyers, the potential effect on the government
would be unduly burdensome. The government deals with all
private citizens and organizations and thus has a much wider circle
of adverse legal interests than does any private law firm. In these
circumstances, the government’s recruitment of lawyers would be
seriously impaired if rule 4-1.10 were applied to the government.
On balance, therefore, the government is better served in the long
run by the protections stated in rule 4-1.11.
Principles of imputed disqualification
The rule of imputed disqualification stated in subdivision (a)
gives effect to the principle of loyalty to the client as it applies to
lawyers who practice in a law firm. These situations can be
considered from the premise that a firm of lawyers is essentially 1
lawyer for purposes of the rules governing loyalty to the client or
from the premise that each lawyer is vicariously bound by the
obligation of loyalty owed by each lawyer with whom the lawyer is
associated. Subdivision (a) operates only among the lawyers
currently associated in a firm. When a lawyer moves from 1 firm to
another the situation is governed by subdivisions (b) and (c).
The rule in subdivision (a) does not prohibit representation
where neither questions of client loyalty nor protection of
confidential information are presented. Where 1 lawyer in a firm
could not effectively represent a given client because of strong
political beliefs, for example, but that lawyer will do no work on the

case and the personal beliefs of the lawyer will not materially limit
the representation by others in the firm, the firm should not be
disqualified. On the other hand, if an opposing party in a case were
owned by a lawyer in the law firm, and others in the firm would be
materially limited in pursuing the matter because of loyalty to that
lawyer, the personal disqualification of the lawyer would be imputed
to all others in the firm.
The rule in subdivision (a) also does not prohibit
representation by others in the law firm where the person
prohibited from involvement in a matter is a nonlawyer, such as a
paralegal or legal secretary. These persons, however, ordinarily
must be screened from any personal participation in the matter to
avoid communication to others in the firm of confidential
information that both the nonlawyers and the firm have a legal duty
to protect. See terminology and rule 4-5.3.
Lawyers moving between firms
When lawyers have been associated in a firm but then end
their association, however, the problem is more complicated. The
fiction that the law firm is the same as a single lawyer is no longer
wholly realistic. There are several competing considerations. First,
the client previously represented must be reasonably assured that
the principle of loyalty to the client is not compromised. Second,
the rule of disqualification should not be so broadly cast as to
preclude other persons from having reasonable choice of legal
counsel. Third, the rule of disqualification should not unreasonably
hamper lawyers from forming new associations and taking on new
clients after having left a previous association. In this connection,
it should be recognized that today many lawyers practice in firms,
that many to some degree limit their practice to 1 field or another,
and that many move from 1 association to another several times in
their careers. If the concept of imputed disqualification were
defined with unqualified rigor, the result would be radical
curtailment of the opportunity of lawyers to move from 1 practice
setting to another and of the opportunity of clients to change
counsel.

Reconciliation of these competing principles in the past has
been attempted under 2 rubrics. One approach has been to seek
per se rules of disqualification. For example, it has been held that a
partner in a law firm is conclusively presumed to have access to all
confidences concerning all clients of the firm. Under this analysis,
if a lawyer has been a partner in one law firm and then becomes a
partner in another law firm, there is a presumption that all
confidences known by a partner in the first firm are known to all
partners in the second firm. This presumption might properly be
applied in some circumstances, especially where the client has been
extensively represented, but may be unrealistic where the client was
represented only for limited purposes. Furthermore, such a rigid
rule exaggerates the difference between a partner and an associate
in modern law firms.
The other rubric formerly used for dealing with vicarious
disqualification is the appearance of impropriety and was
proscribed in former Canon 9 of the Code of Professional
Responsibility. This rubric has a two-fold problem. First, the
appearance of impropriety can be taken to include any new client-
lawyer relationship that might make a former client feel anxious. If
that meaning were adopted, disqualification would become little
more than a question of subjective judgment by the former client.
Second, since “impropriety” is undefined, the term “appearance of
impropriety” is question-begging. It therefore has to be recognized
that the problem of imputed disqualification cannot be properly
resolved either by simple analogy to a lawyer practicing alone or by
the very general concept of appearance of impropriety.
A rule based on a functional analysis is more appropriate for
determining the question of vicarious disqualification. Two
functions are involved: preserving confidentiality and avoiding
positions adverse to a client.
Confidentiality
Preserving confidentiality is a question of access to
information. Access to information, in turn, is essentially a
question of fact in particular circumstances, aided by inferences,
deductions, or working presumptions that reasonably may be made

about the way in which lawyers work together. A lawyer may have
general access to files of all clients of a law firm and may regularly
participate in discussions of their affairs; it should be inferred that
such a lawyer in fact is privy to all information about all the firm’s
clients. In contrast, another lawyer may have access to the files of
only a limited number of clients and participate in discussion of the
affairs of no other clients; in the absence of information to the
contrary, it should be inferred that such a lawyer in fact is privy to
information about the clients actually served but not information
about other clients.
Application of subdivisions (b) and (c) depends on a situation’s
particular facts. In any inquiry, the burden of proof should rest on
the firm whose disqualification is sought.
Subdivisions (b) and (c) operate to disqualify the firm only
when the lawyer involved has actual knowledge of relevant
information protected by rules 4-1.6 and 4-1.9(b) and (c). Thus, if a
lawyer while with 1 firm acquired no knowledge or information
relating to a particular client of the firm and that lawyer later joined
another firm, neither the lawyer individually nor the second firm is
disqualified from representing another client in the same or a
related matter even though the interests of the 2 clients conflict.
Independent of the question of disqualification of a firm, a
lawyer changing professional association has a continuing duty to
preserve confidentiality of information about a client formerly
represented. See rules 4-1.6 and 4-1.9.
Consent to conflict
Rule 4-1.10(d) removes imputation with the informed consent
of the affected client or former client under the conditions stated in
rule 4-1.7. The conditions stated in rule 4-1.7 require the lawyer to
determine that the representation is not prohibited by rule 4-1.7(b)
and that each affected client or former client has given informed
consent to the representation, confirmed in writing or clearly stated
on the record. In some cases, the risk may be so severe that the
conflict may not be cured by client consent. For a definition of
informed consent, see terminology.

Imputation of conflicts in rule 4-1.8
Where a lawyer is prohibited from engaging in certain
transactions under rule 4-1.8, subdivision (k) of that rule, and not
this rule, determines whether that prohibition also applies to other
lawyers associated in a firm with the personally prohibited lawyer.
